Handicap tournament with 5 classes, but 1st class was split: Preti, Cohen, Versin, Warnet and Marguerite were to play in 1st class but to receive odds of 2 moves from other members of 1st class, according to the description of the tournament rules. However, in the list of results, in the 1st round it is not indicated that Preti received these odds from Crampel, though it is indicated that Cohen received them from des Guis. Similarly, Borely was class 2 but in the 1st round it is not indicated that he gave odds to d'Alincourt, who was class 3, though it is indicated that Jeandel (class 2) gave pawn and move to Acloque (class 3). In all other cases, the odds indicated are consistent with the players' classes. Another anomaly, though, is that Cabanellas appears as absent in the 1st class section but played in the 5th class section? One game per pairing, but draws were to be replayed. Only one draw is indicated to have occurred. The reports in La Régence say the tournament took place on 9 and 16 Feb. 1851, but in Séguin's report, he says the final game between himself and Valson took place the next day. This is confirmed by the announcement of the celebratory dinner to take place 17 Feb. 1851 (La Régence, 1851, p.86).
